| Definition | Apnea means absence of spontaneous breathing from any cause. Apnea can be intermittent and temporary, as occurs with obstructive sleep apnea , or prolonged. Prolonged apnea is also called respiratory arrest. |
| Alternative Names | Respiration slowed or stopped; Not breathing; Respiratory arrest; Apnea |
| Considerations | Prolonged apnea (respiratory arrest) is a life-threatening disorder that requires immediate medical attention and first aid. Any episode of apnea, even a temporary one, in which a person turns blue, has a seizure, becomes limp, or remains drowsy or unconscious, requires prompt medical attention. Apnea can occur for many different reasons. The most common causes of apnea in infants and small children are generally quite different from the most common causes in adults. In infants and children, the most common cause of cardiac arrest (lack of an effective heartbeat) is a preceding respiratory arrest. In adults, the opposite usually occurs: cardiac arrest leads to respiratory arrest. |
| Common Causes | Common causes of apnea in infants and young children include:prematuritybronchiolitis or pneumoniaforeign object aspiration or chokingbreath-holding spellsseizuresmeningitis or encephalitisgastroesophageal reflux bronchospasm ( asthma ) Common causes of apnea in adults include: obstructive sleep apneachoking drug overdose, especially drugs such as alcohol, narcotic analgesics , barbiturates, anesthetics, and other depressants (see drug abuse first aid )cardiac arrest Other causes of apnea include: near-drowninghead or brain stem injury cardiac ( arrhythmias ) metabolic disorders nervous system disorders |

Has the person had repeated, brief episodes of apnea? Did the episode end with a sudden deep snorting breath? recent heath history Has there been any recent history of an accident or injury? Has the person been ill recently? other Did the episode occur while awake or asleep? Had there been any breathing difficulty before the breathing stopped? What other symptoms are also present? What medication does the person take? Does the person use street drugs? A general physical examination will be performed, including listening for heart sounds and breath sounds .
